AI protocols help improve fertility performance

Mr Francis has a specific area for AI preparations and management, which is kept clean and tidy at all times.

The site includes the flask, a whiteboard with bull placements map within the flask and plenty of area to handle the semen.

Heat detection collars have been a great asset to Mr Francis, being reliable and effective, which has

semen before retrieving the straw, as the contents will start to thaw within two seconds of being taken out of the flask n Only thaw the number of straws which can be used within 10 minutes n Monitor water temperature continuously n Water should cover all but the top 1cm of the straw helped maintain high submission rates with less effort than previously.

Mr Francis records all calving data, whether there are issues or not. Data includes cow condition when calving, calf detail, calving difficulty, cleansing, milk fever case and late calvers.

Reviewing these records have helped halve the amount and severity of metabolic disorders in the herd.

A handling system which does not increase stress on the cow around AI is important.

Ms Burnby said: “The best way to maximise conception is to have a calm environment and good handling facilities.”

Mr Francis has created a drafting system which provides a low stress environment as the cow drafted for insemination has access to silage and water and can see the rest of the herd when she is being held back for AI.

Ms Burnby said: “Iwan does not normally need to yoke the cows as they usually stand quietly in the race.”

What constitutes a good handling system is different for every farm, said Ms Burnby.

“It might be head yokes, a race, a crush. Each will work well as long as they are set up well and cows are familiar with them.”

Familiarity

For heifers, she recommended running them through the handling system ahead of AI to get them familiar with it.

Ms Burnby also recommended regularly review breeding data –comparing results and taking into account factors such as the AI technician and bulls used on specific days, to see if there is scope for improvement.

She said: “Consider a refresher course for technicians every two years or whenever there are concerns about results.”
